That book is kind of a fun read, but I am not certain that I would recommend it. It's a collection of everything the writers could find from any source that makes Kostunica look bad, but lacking a central narrative and inconsistent in its use of sources. There's an entertaining little appendix, an essay on why Kostunica is not a proper Chetnik (that is supposed to be a bad thing). At best, the book might be used a source of hypotheses that the reader could confirm or reject by doing their own research.
